[Dovecot] Issue with Dovecot v2.0 auto packages

[Stephan Bosch]

Hi,

Yesterday night I upgraded the automated packages built at Xi to the 
latest experimental Debian packages for v2.0. This unfortunately causes 
a problem upon upgrade. I've contacted the maintainer, so this issue 
should resolve itself soon.

The issue manifests as follows:

Setting up dovecot-imapd (2:2.0.11-0~auto+25) ...
ucfr: Attempt from package dovecot-imapd  to take 
/etc/dovecot/conf.d/20-imap.conf away from package dovecot-common
ucfr: Aborting.
dpkg: error processing dovecot-imapd (--configure):
   subprocess installed post-installation script returned error exit 
status 4
   configured to not write apport reports

The Debian maintainer split dovecot-common in various new packages and 
moved config files in the process. Use

ucfr --purge --force dovoecot-imapd /etc/dovecot/conf.d/20-imap.conf
ucfr --purge --force dovoecot-managesieved 
/etc/dovecot/conf.d/20-managesieve.conf
ucfr --purge --force dovoecot-sieve /etc/dovecot/conf.d/90-sieve.conf

to get rid of these errors as a workaround. I did this in combination 
with temporarily purging and removing Dovecot, but that is probably not 
necessary. Once you have upgraded, you will not encounter this problem 
again.

And yes, if you are using Sieve, be sure to install the new 
dovecot-sieve and dovecot-managesieved packages.

Regards,

Stephan.
